. Specification of Letters Patent.

Application filed February 10, 1908.

Patented Aug. 22, 1911.

Serial No. 415,091.

To all whom it may concern:

Be it known that I,"HARLEY CLIFFORD A rman, a citizen of the United States, residing at Ghicago Heights in the county of (look and State of Illinois, have invented a new and useful Improvement in Liquid- Mcters', of which the following is a complete specification.

My invention relates to improvements in liquid meters in which receptacles or chamand emptied, one object being to provide a meter which shall receive liquid in a cohtinuous or in a varying stream, and deliver it in..unitcharges of predetermined and unvarying weight or volume.

Another object is to provide a meter which will receive liquid in a continuous stream and deliver it in unvarying unit charges without interrupting the flow of the entering liquid.

A still further object is the revision of a device of this character capa le of receiving and delivering liquid without the employment of valves or equivalent devices.

' In the accompanying drawing, Figure 1 is a vertical viewof a meter partly in sec tion on the line XX of Fig. 2; Fig. 2 is a vcrtical view of the meter partly in section talien at right'angles to Fig. 1; Fig. 3 is a view in cross section of the lower end of the 'inlet nozzle, and Fig. t is a cross sectional view thro'ugli one ofthe bends in the siphon 'pi es as at b'Fig. 2.

eferring to the accompanying drawing, the meter comprises'two closed measuring compartments and A, Fig. 2, placed side by" side, the compartments separated from each other by the wall or partition 0.

These compartments form.- the body of the meter. lh'e.y are supported by the legs .B B.

An iriletnozzle, a, supported above the" coinpartnients by the arms d d is provided with a suitable connection as at e'for a hose or pipe, (not shown) adapted tosupply liquid to the meter. A tipping member "f Such member consistsfof divergent passages g and g separatedby the-dividing diaphragm '7' which swings under the lower end,.a,'of

the inlet nozzle. The member is "rigidly mounted on the rod, h, which rod is ]0urnaled in bearings 71, 2', in the arms (Z and d.

, use of the lugs is optional.

" in eyes r and r. I supported in any suitable manner asshown The passages g and g in the tipping member f, are provided with laterally extending pockets l: and 7c respectively, which may be conical in shape. The center of. gravity of the tipping member is above bearings i i, so that when the member is tipped a slight distance past the vertical center linepit will fallby gravity until its upper edge strikes a lug Z on the'inlet nozzle, and, there remain until rocked backa slight distance past the center when it will swing in the opposite direction until its upper edge strikes the lug Z on the opposite side of the inletnozzle. The The lower ends of the passages g and g of the tipping member are adapted to discharge liquid into the hoppers m and m communicating with the compartments A and A respectively.

The rods 0 and 0 are loosely connected to the tipping member in any suitable manner, as by the links '0 and o pivotally secured to the rods and to the tipping member by means of pin joints at n n and n Figs. 1 and 2. The rods 0 and O are received in necks q and g communicating with the respective measuring compartments, and carry light metal or cork floats which are suspended in the measuring compartments A and A respectively. The float p, suspended in com artment A, is clearl shown in Figs. 1 ant 9.. These floats are ree to move in the necks q andg, being guided in their movement by the rods 0 audio which slide The eyes 7* and 1" are at Fig. 1. I

The bottoms of the n'ieasuring com artments A and A are preferably incline h and terminate in the wells t, t. In order to dis charge the contents ofthe, respective co n partments 1' preferably employ the bentsiphon pipes u and u. These pipes extend from points near the bottoms of the wells at it up through. the tops'of the measuring compartments and return outside the measuring compartments to points wand w be ldw the bottom of the wells as shownin Fig. 2. These tubes act as siphons to draw all of the liquid from the compartments A and'A.

Tlie meter operates as follows: Liquid enters, ;the'inlet nozzle by means of any suitable connection secured thereto zit/c.

the opposite side of the nozzle.

and isdischarged into the passage 9 or g.

Assume that the inlet nozzleis discharging into 'the passage g. After filling the pocket is carried by the tipping member and comn'mmcating with the passage through the opening 2, the liquid is delivered into the 1 hopper m and is led to the measuring compart1nent A. The .(ZOIIIPHItl'DQIlt A Wlll be above the top of the measuring compartment, I

it will raise the float p which pushes up on the rod 0, and thereby throw the center of {,avity of the tipping member over a little instance past the center line. The tipping men'1ber will then fall by gravity until its "upper. end strikes the lug l on the inlet nozzle, and the liquid discharged from the nozzle will then flow into the passage g because the diaphragm j has been moved to After filling the pocket is, the liquid will pass through the hopper m into the measuring compartment A. At the same time that the tilting of the tipping member operates to elevate thepocket is which is full of liquid,

the liquid contained therein is suddenly thrown into the measuring compartment A,

.the'contents of which are already on the point of spilling'through the siphon pipe u at its upper bend b. The sudden increase in head caused by this extra liquid previously stored inthe pocket 70, immediately,

starts the siphon, which will continue until the measuring compartment A has been completely emptied. Meanwhile the liquid is'flowing-into the measuring compartn'ient A after filling the pocket .73 and when the liquid reaches. "the level y, the tipping dcvice will be thrown back to its former p01 sition (shown in Fig. 1) by a similar operation of the float in the measuring compartrncut A; the siphon it will be started-by the liquid in pocket lc; and the stream-will be again directed into the iueasurmg compartment A which has been completely emptied of its liquid, whilethc n'ieasm'ing compartment A was filling. Practically the same amount of liquid will have passed through the meter'during each complete cycleior each time the two compartu'icnts are emptied, or if compartments A and AJ are of exactly the same capacity, the same amount of liquid will have passed through the meter each time a siphon o )erates.' A registering'dcvice (.1 may be'connccted to the rod h h and so arranged as to register the number of. cubic feet or pounds which have passed through the meter.

Ordinarily during the interval that the ing con'ipartme'nt to the other by the tipping (1, than when the supply was less and a mere trickle of liquid was flowing-1;. Such a condition would ire rise to an error because more liquid would be discharged each 5 time a siphon operated when the supply was rapid than when the supply was slow. flo remove this objection. I have provided the lower end of the inlet nozzle a with the shape shown in Fig. 5:3. For instance the the nozzle is elongated and provided with l hollow noses projecting from the opposite side walls of the nozzle, the noses being in -conm'mnication with the interior of the nozzle. As the dividing diaphragm j of the tipping. member, 7, passes the lower end of the inlet nozzle (1 from left to right, it: will pass through the positions shown by the dotted lines 1--l, 22, 33, et-4-, 5-5 and 6, 6. \Vhcn the said diaphragm is in position 1 1 all of the liquid [lowing will flow to, the passage g, but when said diaphragm is in position 5, 5 onlya small float 79 may be so adjusted that just before the liquid reaches the lcvel y, the tipping diaphragm j will be in the position 5, The center of gravity of the lipplllgdlltllllycrtica'l center line, but not far enough past to overcome the friction of the bearings Z Z. Only a small stream of liquid will now be [lowing to passage g, and when a [few only a'small stream remains to be intercepted and directed into the opposite com.- partmcnt A A. Under these conditions only a small stream of liquid is linally cutott'in rapidly or slowly through the inlet nozzle a, aml-the'error arising thcrciron'i is reduced to a minimmn. v

I have provided the bends in the si hon pipes a andof' with elongated sections having the same area as the rest of the siphon This enables the siph'ons to be started by a much smaller increase in head, thus I'e ducing the amount of water to'bc carried in the pockets 7:: and is used to start the siphons.

The pockets 7c and k are preferably made conical with contracted necks at the ends where may join the passages y'and respectively, as shown at 2 Fig, l and 2 Fig. 2, so that, when full, the amount of liquid in each pocket will bovcry nearly the same pocket may be higher at one tim'c than anothcr'as might be thecase if the meter member will be tlirown over so that the said.

Theiao were jarred, or tipped more or less. "The error due to difi'creut heights of liquidlin' this small contracted neck is thus made neglig'ible.

l The tops of the measuring compartments are made with a gradual rise from the sides toi'vard the necks and {1' and toward. the hoppers m and-m1, so that the air given full opportunity to escape, and also in order to' irercnt air from being entrained in the measuring com pa rtm ent The level of the liquid is brought up to thej'points y and y, well above the tops of the measuring compartments before the tiping device is allowed to operate in order to insure the complete filling of the measuring coniparti'nents, and also thatlthe error due todifi'ercnces in the height of the level, of 'thejliquid at the time the siphon starts may be made negligible because such variation will then take place over the small. areas of the ho pcrs m and m and the necks Q and q instea of over the entire areas of the respective measuring compartments. The bottom of each of the measuring compartments A and A slopes gradually down- Ward towardthe smallwells t and t re? sfpectively, in which theshort ends of the siph onfpipcs inserted. .Tl1is insures an 9 almost complete emptyingof each measuringcompa-rtment, the only liquid left being the 'very'small amount belovt the short end f the si hon pipe. It also increases the accuracyo the meter because anyvariationin the'level of liquid at the time the slpliorr stops running will take placeover' the small area of the'wells t and t,; and any error arising therefrom will not 'be appreciable What I claim as In Q to secure by Letters 1 atent is as follows 1 Ina metering device comprising meas- -uring compartments, dividing means separating the measuring compartments and a tilt member affording passage for the -matefr1'al being measured and for directing thefsame' to: the measuring compartments,
